.Convertible Childs High Chair and Crib,

. of whichthe following is a specification.

I My invention relates to a childs folding chair in which a'crank and connecting rod are employed in folding it, and which in one position is an ordinary childs high chair, while in another position it is a crib with head and foot boards. and its arms spread wider apart than in the chair form, with an inclosing fence for the retention of bed clothm 31s a crib for a child is of little use unless it can be rocked or given an oscillatory movement, a method of producing an oscillatory movement longitudinally'of the crib will be shown, but it should be understood than no claim is to be made in this application for any rocking or oscillating movement. The oscillating movement can be given by an attendant and a 7 method is shown by which it may be produced by a motor (not shown,) that may be located underthe chair seat.

The several parts are shown in the accompanying drawing in which,

Figure 1 is a side elevation of the device in the form of a high chair, the seat and back in heavy lines showing it at the forward limit of its oscillating movement, and in dotted lines at its rearward limit. Fig. 2 is an edge view of the crank which is used in folding the chair, and a part of its rod for connecting with the chair back. Fig. 3 is a sectional view of the socket through which the crank shaft is inserted. Fig. 4 is a plan of said socket. Fig. 5 is a side elevation of the device folded into the crib form, the supporting legs being omitted. Fig. 6 is a front elevation of the seat, the back, the arms spread apart, the head board nearly at right angles with the back, and the foot piece in part. Fig. 7 is a side elevation of the inner side of one of the chair arms spread outward, the seat being in section. Fig. 8 is a front elevation of the device as a chair. Fig.

9 is an elevation of the back side of the device in the form of a chair, and showing how its lower part may be utilized for wardrobe purposes. Fig. 10 is a section on the line 6, 6, of Fig. 8. Figs. 2, 3, 4 and 11, are upon an enlarged scale.

Similar numerals and letters indicate like parts in the several views.

The chair frame is formed of four legs 1,

connected together with stretchers 2, the legs at opposite sides of the seat being surmounted with caps 3. The seat frame which supports the arms 4, back 5, head and foot boards 6 and 7 respectively, is separate from the chair frame but is supported upon it by means of four rolls 9. The grooved rolls 9, run in suitable inclined tracks 13 in a cap piece 3 and in the seat side rails 8 to produce a curved reciprocating motion of the seat.

The boundary of each slot that is not used as a track has a little out out of it, as 13, for permitting the entrance of the roll in assembling the parts. The seat has at its front a roller 16, which is journaled at 17 in the pieces 8, from which roller, hangers 18, depends, said hangershaving at their lower ends journals 19, from which the foot board arms 20, extend. The foot board can be adjusted relative to the hangers 18, by means of two rods 21. One end of each rod is connected with the foot board 7, by means of a screw eye 22, and the other connected with a hanger 18 by bolts. Each bolt has a head 23, and nut 24.

Near'the rear part of the seat, a piece 25, is rigidly secured between pieces 8, and one 25 near the front. The rear of the seat is provided with a roller 26, which is journaled at 27 in the pieces 8, from which roller,

chair back posts 28, extend upward to the hinge joint 29, beyond which the head board posts 30, extend the required distance. Chair back pieces 31, 32 head board 33, stretchers 34 and filling pieces 35, may be applied as the taste of the maker calls for. arms4 are supported upon the posts 36 and 37, the latter central ones having secured to the outer side of each, a socket 38, by means of screws or bolts 39, in which sockets crank shafts 40, are journaled, each being provided with a crank 41. Upon the inner sides of posts 37 a plate 42, is secured, which is engaged by the bolts 39, and through which plates a crank shaft extends. From each crank pin of the cranks 41, a connec tion 43, extends to an arm 43*, extending from a post 28 of the chair back. When the cranks are in the position shown in Fig. 1, the chair form is preserved, but when they are revolved a half revolution, as in Fig. 5, the crib form is produced. The head board posts 30, are provided with bands 44, of thin The i band nietal, which are loosely mounted, from which side rails 45, extend to the chair arms where they are pivotally connected to the arms with cotter pins d6. (See Fig. 5.) In addition to serving as-a fence, the rails 45 serve to swing the head board at an angle with the chair back in folding the chair into the crib form. (See Figs. 5 and 6.) Rails 4E7 similar to rails 45, are extended from the head board to some part near the seat, as to the screw 48, in the seat side rail. From the rails 15 130 rails 47, wires l9, extend and form a fence for holding bed clothing within the crib sides.

The rails 45 are shown only in Figs. 5 ZLIlClG, and the rail 47 in Figs. 5 and 10. A similar fence may be arranged from the forward ends of the arms toward the foot board and be secured to the arms in a like detachable manner. They are of light weight and are easily detachable by means of cotter pins, 46.

From the rear of the seat, arms 53, are secured to the posts :28, and extend downward, from which a rod 53 extends to a bracket 54;, .upon each foot board hanger 18. The rods operate to throw the foot board hangers into a position substantially parallel to the chair back, when the device is changed to the crib form. The arm posts 36 are hinged to the seat side rails 8, with hinges 55, (see Fig. 1,) and swing outward as the back is swung into the crib position. This is effected by a hinge 56, upon each post 37, the lower leaf of which is secured to the side rail with a single screw 57, and the upper leaf of which is secured to a crank shaft in such an eccentric position with the screw 58, that as the cranks are turned from the position shown in Fig. l to that shown in Fig. 5, he screws 58 will push downward upon the screws 57 and throw the arms outward as is shown in Fig. 6. The chair back and head 1 board posts 28 and 30, are provided at their hinge joint with a sliding bolt 59 and two keepers 60, by means of which the chair. back part and head board part can be held parallel with each other. v A table 61, can be placed across the'front ends of the arms at. 7

For utilizing the space below the seat for a childs play things or for Wardrobe purposes, drawers 71, may be inserted. Above .zontal position.

the drawers doors 7:2, may be arranged for It should be observed that the chair back can be inclined at, various angles: between those illustrated. This can be effected by means of a series of holes 77, in the face of the socket 88, and a spring controlled pin 78, fixed in the spring leaf 79, which engages the socket. The space uponthe front below the upper stretches between the legs and upon the sides below the cap pieces are to be inclosed with veneering, as 7 9 but it has mostly been omitted, nails 80, being shown by which it may be secured in position.

Having described my invention, what I claim and desire to secure by Letters Patent, is,-

. 1. In a v seat frame, arm posts hinged to the seat frame to swing in a vertical plane, pivotally mounted back posts adjustable into a nearly horizontal position and means actuated by the back posts for swinging the, armposts outward when the backposts are swung to said nearly horizontal position.

2. In a convertible chair having a chair seat frame, arm'posts hingedtothe seat frame to swing in 'a vertical plane, pivotally mounted back posts adjustable into a nearly horizontal position,crank arms between the arm posts at opposite sides of the seat, a: rod from each crank arm to a chair back'post, hinges pivotally connected by one leaf toopposite chair seat frame sides and by the other leaf in an eccentric position relative to the axis of a crank arm to the inner end of a'crank arm shaft and adapted to swing the chair arm posts outward when the chair back posts are swung into said nearly hori- CARL JAGOBSEN.
